Why Regular Data Recovery Tools Can’t Restore Files from RAID

Conventional hard drives store user data by writing it sequentially across the disk surface, which means an entire file is typically located on a single drive. In contrast, when data is written to a RAID array, each file is split into multiple fragments. These fragments are then distributed and written in sequence across all the drives in the array. Depending on the configuration, fragment sizes can range from 2 KB to 2 MB, so every file is physically stored across several disks at once.

This approach significantly increases read and write performance — after all, writing two halves of a 1 GB file to two drives simultaneously is much faster than writing the full 1 GB to a single disk. However, this same mechanism makes file recovery far more complex.

Different RAID levels use different methods to distribute and protect data. On top of that, manufacturers like Buffalo often add their own proprietary structures and variations. As a result, data can be written to disks in many different formats, and each requires a specific approach during recovery.

Are there any recommended steps to take after detecting or suspecting data loss on a NAS Buffalo TeraStation TS-IX4.0TL/R5 device?

If you suspect or detect data loss on a NAS Buffalo TeraStation TS-IX4.0TL/R5 device, here are some recommended steps to take:

1. Stop using the device: As soon as you suspect data loss, stop using the NAS device to prevent any further damage or overwriting of data.
2. Assess the situation: Determine the extent of the data loss and identify any potential causes. Check if the data loss is limited to specific files or folders or if it affects the entire NAS device.
3. Check hardware and connections: Ensure that all the hardware components of the NAS device are properly connected and functioning. Verify that the network cables, power supply, and hard drives are securely connected.
4. Restart the device: Try restarting the Buffalo TeraStation to see if it resolves any temporary issues. Sometimes, a simple reboot can fix minor glitches.
5. Check for firmware updates: Visit the Buffalo website and check for any available firmware updates for your TeraStation model. Updating the firmware can address known issues and improve device performance.
6. Verify data integrity: Use the built-in RAID management software or utility provided by Buffalo to verify the integrity of the RAID array. Check for any degraded or failed drives and replace them if necessary.
7. Restore from backup: If you have a recent backup of your data, restore it to the NAS device. Ensure that the backup is not corrupted or affected by the same issue that caused the data loss.
8. Contact Buffalo support: If you are unable to recover the data on your own, contact Buffalo support for further assistance. Provide them with all the relevant details and steps you have taken so far.
9. Consult data recovery experts: If the data loss is critical and cannot be recovered through normal means, consider consulting professional data recovery services. They have specialized tools and expertise to recover data from various storage devices.

Remember, it is crucial to have regular backups of your important data to minimize the impact of data loss incidents.

How to Remove Hard Disks from Your NAS and Connect Them to a PC

Although the NAS TeraStation TS-IX4.0TL/R5 can be accessed over the network, you still need to remove its hard disks and connect them directly to a Windows PC. Only then can the recovery software properly scan and analyze the drives. Follow these steps:

1. Power off the NAS and disconnect it from the power source.

   WARNING! Before removing any drives, carefully read the device manual. Improper actions may damage both the NAS enclosure and the hard disks in the RAID array.

2. Remove the hard disks one by one, gently sliding each drive out of its slot. Remember that hard disks are highly sensitive: any impact or drop can cause serious physical damage.

3. Label each hard disk according to its position inside the NAS. The order of the drives is crucial for correct RAID reconstruction.

4. Connect the drives to your computer. In this video, we explain which ports you can use to connect hard disks and what to do if your PC does not have enough free connectors.

   How to Order Remote Data Recovery

Step-by-Step Data Recovery with Hetman RAID Recovery

This program restores data from damaged RAID arrays and is fully compatible with Buffalo TeraStation TS-IX4.0TL/R5. Each hard disk in the array contains technical metadata describing how files were written. When launched, Hetman RAID Recovery analyzes this metadata, automatically reconstructs the damaged array, and provides access to its contents. After that, you can browse the recovered disk and save your files. The program can also restore files that were accidentally deleted from the network drive.

How to recover data from a Buffalo

TeraStation TS-IX4.0TL/R5 has 4 HDD slots, and it supports the following array types:

• RAID 0;
• RAID 1;
• RAID 5;
• RAID 6;
• JBOD;

NAS supports:

• exFAT, VFAT, FAT 12 / 16 / 32;
• NTFS / ReFS;
• APFS / HFS+;
• Ext2 / 3 / 4 / ReiserFS / XFS / UFS / ZFS / Btrfs;
• VMFS / HikvisionFS;

How to Safely Recover Data from Disk Images

This utility allows you to create a complete copy of a disk and work with the disk image instead of the physical drive. This approach helps protect your data from:

• Overwriting during the recovery process;
• Additional data loss caused by bad sectors;
• User errors.

To create a disk image, follow these steps:

1. Ensure you have enough free space to store the image. Its size will typically match the size of the original disk.

2. In the main window, select the target disk and choose Tools - Save Disk. You can also select multiple disks if needed.

3. When the Image Creation Wizard opens, select whether you want to save the entire disk or only a specific region. Adjust the settings and click Next.

   

4. Choose the directory where the image will be saved. You may select any available disk connected to your PC or upload the image via FTP.

   

Where Are the User’s Files Actually Stored?

The Buffalo TeraStation TS-IX4.0TL/R5 network-attached storage keeps OS Linux operating system files on a separate RAID 1 (mirrored) array. Usually, all NAS systems create several volumes on every hard disk, and the first of them takes up to 2 Gb of space. This is where operating system files are stored. Other volumes are united into a RAID array where user’s data is written.
